摘要

•Common methods for sentiment and emotion recognition are in the Euclidean space.•Some data exhibit hierarchical structures, well modelled in the hyperbolic space.•Hyperbolic learning is proposed to improve the recognition task.•Hyperbolic models outperform classical Euclidean methods on benchmark datasets.
